• Performing a fuzzy search may retrieve terms with similar spellings: karachi : (summa OR ((samma OR (ssummar OR (sssummary OR lsummahry))) OR summahr))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: karachi : (summa OR ((samma OR (ssummar OR (sssummary OR lsummahry))) OR summahr)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "karachi : (summa OR ((samma OR (ssummar OR (sssummary OR lsummahry))) OR summahr))".
• Adding a wildcard symbol may retrieve word variants: karachi : (summa OR ((samma OR (ssummar OR (sssummary OR lsummahry))) OR summahr))*.
